    Hi Anonymous ,

    so here is a third variation:

     

     

    Difference in Month = 
VAR _StartLessThanEnd =
IF (
    OR ( 'Table'[Start], 'Table'[End] ) = BLANK (),
    BLANK (),
    DATEDIFF ( 'Table'[Start], 'Table'[End], MONTH ) + 1
)
VAR _EndLessThanStart =
IF ( 
    OR ( 'Table'[Start], 'Table'[End] ) = BLANK (),
    BLANK (),
    DATEDIFF ( 'Table'[End], 'Table'[Start], MONTH ) + 1
)
RETURN
    if ( 'Table'[Start] < 'Table'[End], _StartlessThanEnd, _EndLessThanStart)

     

    With kind regards from the town where the legend of the 'Pied Piper of Hamelin' is at home

Hi Anonymous 

if the absolute number in 'Test Term' is correct and you want only to get reed of the negativ sign then use the following measure:

Difference in Month =
IF (
    OR ( 'Table'[Start], 'Table'[End] ) = BLANK (),
    BLANK (),
    ABS( DATEDIFF ( 'Table'[Start], 'Table'[End], MONTH ) + 1 )
)
